Waveshare UPS HAT (D) for Raspberry Pi, 21700 Li Battery, 5V Pogo Pins

The Waveshare UPS HAT (D) is engineered to provide an robust uninterruptible power supply solution for various Raspberry Pi models, specifically the 3, 3B+, and 4B. Its innovative pogo pin design facilitates a seamless, solderless connection, streamlining integration into your projects. This HAT requires two 21700 Li-ion batteries (not included) to function, offering a substantial power reserve.

Equipped with an advanced Li battery charging chip, the HAT incorporates dynamic path management to ensure a consistently stable 5V power output, even during simultaneous charging and discharging cycles. Communication via the I2C bus allows developers to precisely monitor key battery metrics such as voltage, current, power, and remaining capacity. Critical safety features include multiple battery protection circuits against overcharge, over-discharge, over-current, and short circuits, safeguarding both the batteries and the connected Raspberry Pi. Furthermore, an onboard MCU intelligently manages power connection detection and automatically boots the Raspberry Pi, enhancing system reliability.
